Automotive Full Bridge MOSFET Driver

The A3941 is a full-bridge controller for use with external N-channel Power MOSFETs and is specifically designed for automotive applications with high-power inductive loads, such as brush DC motors.
A unique Charge Pump Regulator provides full (>10 V) Gate drive for battery voltages down to 7 V and allows the A3941 to operate with a reduced Gate drive, down to 5.5 V.
A bootstrap capacitor is used to provide the above-battery supply voltage required for N-Channel MOSFETs An internal Charge Pump for the high-side drive allows DC (100% duty cycle) operation.
